The "30 Rock" star says he's gearing up for his role in the upcoming film adaptation of the hit Broadway musical by taking singing lessons. "You have to," he tells Vulture. "You have to take it seriously."

In "Rock of Ages," Baldwin plays Dennis Dupree, the owner of the Bourbon Room club, where small-town girl Sherrie (Julianne Hough) takes a job while pursuing her dreams of becoming an actress.

In the Broadway version of the show, Dennis sings REO Speedwagon's "Can't Fight This Feeling," but Baldwin, who hasn't seen the stage musical, isn't quite sure which songs he'll be warbling on screen.

"I think they have us all sing something," he says of co-stars Hough, Tom Cruise and Mary J. Blige. "I think I'm going to sing, thankfully, something very modest; I might sing 'Yeah, yeah, yeah,' or something like that."

Does this mean we'll get to see Baldwin dancing as well? "No. It's not that kind of thing," he says. "It's not 'Glee,' it's rock and roll."

Can somebody confirm or deny that Lucas Wynne (http://twitter.com/#!/lucaswynne) will be playing the male lead role? From what I can find around the net he's an indie actor who used to do music and now does some comedy writing. I think it would be pretty exciting to see a fresh (and undoubtedly attractive) face like that on the big screen.

I follow Alec so I have been reading everything about Rock of Ages since rumors he would be in it came out. By coincidence I live in Murfreesboro and actually saw Lucas Wynne perform at an open mic in Tennessee about a year back. At the open mic he mentioned at the time he was considering a bit of a career change and making music his "passion" and did a little bit of acting that was to say the least impressive. He reminds me of Jonny Depp in terms of a guitar-playing actor. I don't know if the rumors are true, but I hope they are. Keep in mind he says on his twitter account in a tweet to Adam Shankman, the casting director... AND I QUOTE "@adammshankman Auditioning for RoA soon. Hopefully my Nashville days help. Otherwise I'll be hitting the stand-up comedy circuit this year." which would imply he hasn't snagged the role yet. But sometimes Hollywood doesn't want to release casting news right away, so who knows. CROSS YOUR FINGERS! =D

How silly you are Anna. I'm sure you dislike Cruise for more that just his movies...otherwise who misses a movie with a fav actor just cause another actor?? Besides you obviously haven't seen all his movies. Did you not see All the right moves? Top Gun? Eyes wide shut? Collateral? The lase Samurai? A few Good men? Jerry Maguire? Born on the forth of July? You people who claims Cruise has no talent are haters and simply are letting your annoyance with the actor color your perceptions of his acting skill.

I love Alec and I am glad to hear he is going to try to sing. I can't stand Tom Cruise though and he is not a singer etc. The lead in this film should at least have talent to start with. Cruise isn't musically inclined and I don't count dancing like Less Grossman a talent. As much as I love Alec I would have to catch this on DVD – I won't pay money to support Tom Cruise in anything. I haven't cared for his acting since before the first Mission Impossible film came out.

I punched him And knocked him down on the set of the hunt for red October. Apparently he was having a problem and decided messing with A stressed out US submarine sailor was a keen idea. After he got back up... He ran down the stairs of the sub mock up and out the door... He didn't come back that day. Anyway.. Not sure if he is still like that but... He owes me an appology for saying F U to me in front of Scott Glen. Finsterthecat@yahoo.com

Baldwin was great in Hunt for the Red October. Problem was, he didn't get the sequel, Harrison Ford did (for which Tom Clancy, the writer was furious, believing rightly that Ford was too old to play Jack Ryan). After that career downer, Baldwin went insane, became a raving liberal and reactionary male version of Joan Collins (and his family fell apart) and now he's stuck in television hell.

Richard, interesting Fox News spin on Baldwin's life and career. Sadly for you (and just like your favorite propaganda outlet), you've got all your facts wrong from the start: Baldwin turned down the next Clancy movie - it was his choice, genius.
